But I digress, reed curves are done in stages that you get accustomed to eyeballing closely. There is the liftoff curve which is very gentle and starts just above the tuning range of the tuning wire. Next is the = midcurve which sets how the reed tongue will "roll" down to cover the embouchure in = the shallot. The midcurve is ideal when the tongue will go down and not contact the shallot during full excursion. Then end curve is sometimes = added to run up the harmonic content where desired. While I have listed three regions of curvature they should all be blended evenly and you almost end = up with a nice parabolic quadrant curve. Al Sefl

I believe the book was by Milne. (I think we actually have a copy at one of our locations). I also believe that it was reprinted on several occasions, but am not sure as to whether it is still available. As I have 2 sons (and a son-in-law) just coming into the business, I would like to find additional copies. I would also like to find 3 more copies of "The Organ Today" by Norman (either edition), along with several other books. If anyone finds copies of any books (at realistic prices), I would be glad if they emailed me directly. Thanks, Hugh

It's a fairly practical book when you get used to the technical writing style of the early 1900's. I think you will need to work out the stop = list yourself, as you already are. I worked with Richard Schneider to decide on a stop list. He was very helpful. -Bruce Ledet
(back) Subject: Paper Organ Project (was: Making reeds) From: "Michael Schnell" <email@example.com> Date: Mon, 29 Jan 2001 22:32:35 -0600 >Michael, how about a report on your experience with the paper pipes? >Larry Chace <snip> Larry Chace asked for a "State of the Project" report last week. I'm = sorry I haven't replied until now, but I wanted to try to think through what I wanted to say about it. So here goes... I originally started out thinking about this project because I finally realized I really didn't like to play the piano any more, but really preferred the organ. I have been a roller skater most of my life and had my first contact with pipe organs at the Hub Rink in Norridge, Illinois where I skated to the music of Leon Berry. During junior and senior year in high school I was in contact with an organ maintenance company and = could have almost put together an organ for free but my dad refused to have = "that junk" sitting around the basement, so out it went. After college I got married, raised kids and pretty much left skating and pipe organs behind, or so I thought. Fast forward twenty years. My kids are grown, I'm single, and looking for something new to do. About this time someone in my church offered me a Conn spinet if I would come and get it. I brought it home, began to play it, and realized I could play it better than I could play the piano. At the same time, one of my old skating friends told me that the North Ave. Rollerway in Melrose Pk., Illinois had a pipe organ. I went skating one night and I was smitten again (you know how this works...). Well, now I'm playing the organ but since I'm in a townhouse, there's really no way to get an organ in here so what to do? Enter Mark Wick's book on organ building. I figured if I couldn't get a whole organ in here, I could at least make a few ranks of pipes and hook them to the Conn. So = I began to read. The biggest challenge in the beginning was to translate the tools and materials into what today's equivalents would be. "Cartridge paper" turned out to be 80# artists drawing paper used for the pipe body, "glass paper" was sand = paper, the glue, Elmer's, and so on. He suggested procuring old cigar boxes to get wood for the languids and lips, but all I had was pine cut into strips so I used that. I use a scroll saw to cut the languids out and a grinder to finish them. Mandrels can be anything from dowel rod to cardboard mailing tubes. I got a set of round plastic measuring spoons for $1.57 at the grocery store. I use them to shape the pipe feet. I've got several sizes so it looks like I'm good up to a 4' pipe. The pipes themselves are remarkably sturdy. After rolling them up about 3-4 times depending on size, and painting the insides with some leftover latex = paint, they come out rather hard. I also painted the outsides with white latex to clean them = up a bit. Use a thin bristled brush, probably a watercolor type and this will minimize any streaking. The hardest time I've had making them is learning how to voice. I've = read a few books and watched a few AIO videos, but I'm far from mastering that art. With metal pipes, all of the components, can be moved around within reason to make the pipe speak. Not so with the paper pipes. Here the languid is stationary and both lips = have to be moved around to get the best speech. Without being able to move the lips in or out, other things, such as the bevel (or lack of it) on the languid, the flue width, or the cut up, becomes much more important. Most of the mouths have been higher than a quarter mouth, but it could just be my lack of experience. I had originally planned to make a full rank, and then procure a DE, one rank windchest, and some kind of blower/regulator. I actually find that some kind of voicing jack may be what I really need first. Since I have none of that equipment, I've been voicing them using a human (me). That's plenty loud for my small room even with a vaulted ceiling. This leads me to where I am today. The discussion on reeds piqued my interest. If I can make flute, string, and reed tone, I could possibly make most of an organ out of paper. I think I'm going to change gears and begin to make some string pipes and experiment with reed tone as a proof of concept exercise. I'm probably going to need the help of everyone on the list since I'm not in organ construction for a living, so my thanks in advance to all of you who are willing to share what you've learned. I may never get the whole thing built, but I will have learned a lot in = the process. I'm excited about experimenting even though it takes many hours to make each pipe. If anyone has questions, I would be glad to answer them as best I can. My goal is to not only make these pipes but to give something back to advance organs and organ building. As Al Sefl would say, I'm trying to cultivate " a tinkerer's spirit". Thanks, everyone. Mike Schnell Schaumburg, Illinois "Whatever your hand finds to do, do it with all your might."
